hi my speakers in my car have starter to crackle when the volume goes over 25 iv connected another speaker up to it it still crackles, so i connected it to the back if the deck and it still crackles, iv even tried changing the deck, iv resently put a new 4wd batt in it its running 2 batterys could that affect it? im really confused cheers
i have similar front speaker noise. Sounds to me like it's your speakers that are blown. Is the connection on the speaker good and solid? i can't see 2nd battery being your problem.
